Functions | |
| System::Void | Cancel () |
| Attempts to cancel command execution. Cancel may be called on a separate thread after the commands Execute method has been called and before Execute has returned. If successful, an exception is thrown from the Execute method. If there is nothing to cancel, nothing happens. If command execution is in process, and the attempt to cancel fails or is not supported, an exception is thrown. | |
| __property System::Int32 | get_CommandTimeOut () |
| Gets the number of milliseconds to wait before terminating the attempt to execute a command and generating an error. If the provider does not support the timeout capability, 0 is returned. | |
| __property NAMESPACE_OSGEO_FDO_COMMANDS::ParameterValueCollection * | get_ParameterValues () |
| Returns an FdoParameterValueCollection. If the command requires parameters, the literal values to bind to each of those named parameters must be added to this collection. | |
| __property NAMESPACE_OSGEO_FDO_CONNECTIONS::ITransaction * | get_Transaction () |
| Gets the transaction in which the command executes. | |
| System::Void | Prepare () |
| Validates and optimizes the command for execution. Calling this method is optional, but recommended if bound to different sets of parameters and executed multiple times. | |
| __property System::Void | set_CommandTimeOut (System::Int32 value) |
| Sets the number of milliseconds to wait before terminating the attempt to execute a command and generating an error. If the provider does not support the timeout capability, then attempting to set a timeout will result in an exception. | |
| __property System::Void | set_Transaction (NAMESPACE_OSGEO_FDO_CONNECTIONS::ITransaction *value) |
| Sets the transaction in which the command executes. | |
Variables | |
| public __gc __interface | ICommand |
| The FdoICommand interface defines behavior common to all commands in FDO. In order to be executed, commands must have an association to a connection. Commands can also be optionally associated with a transaction if the connection supports transactions. The parameter values collection allows values to be specified for commands that support expressions and/or filters. | |
